Creating events with Thunderbird the attendees were missing in the invitation mail.

Looking at the events the following difference can be seen: iOS:

ATTENDEE;CN=felix@derklecks.de;CUTYPE=INDIVIDUAL;PARTSTAT=NEEDS-ACTION;RSVP=TRUE:mailto:felix@example.com

Lightning:

ATTENDEE;PARTSTAT=NEEDS-ACTION;ROLE=REQ-PARTICIPANT;RSVP=TRUE:mailto:felix@example.com

in mail.py the following is done:

      for attendeeProp in calendar.getAllAttendeeProperties():
            params = attendeeProp.params()
            cutype = params.get('CUTYPE', (None,))[0]
            if cutype == "INDIVIDUAL" :
                cn = params.get("CN", (None,))[0]
                cuaddr = normalizeCUAddr(attendeeProp.value())
                if cuaddr.startswith("mailto:"):
                    mailto = cuaddr[7:]
                    if not cn:
                        cn = mailto
                else:
                    emailAddress = params.get("EMAIL", (None,))[0]
                    if emailAddress:
                        mailto = emailAddress
                    else:
                        mailto = None

                if cn or mailto:
                    attendees.append( (cn, mailto) )

But reading RFC5545 there is the following:

   Description:  This parameter can be specified on properties with a
      CAL-ADDRESS value type.  The parameter identifies the type of
      calendar user specified by the property.  If not specified on a
      property that allows this parameter, the default is INDIVIDUAL.
      Applications MUST treat x-name and iana-token values they don't
      recognize the same way as they would the UNKNOWN value.

Therefore the following patch should be applied:
